rapping-machines of the type for which the present invention" is adapted are well known in the art and, therefore, only the essential elements of the wrapping' mechanism are herein shown and described.

Referring first to Fig. 1 of the drawings, 2 designates the hollow, rotatable spindle of the wrappingunachine, through which the wire or other core passes during the wrapping operation, and 3 is the revolving flier for winding the yarn about the axis of the spindle to cause it to be wrapped around the wire or other core. The vertical spindle 2 is ournaled in a bearing 4:, forming a part of or attached to the main frame of the wrapping-machine, and carries a pinion 5 held fast thereon by suitable means such as the set-screw 6. Meshing with the pinion 5 is a driving-gear through which the spindle 2 is rotated to revolve the fl er 3 about the wire to be wrapped. The flier 3 is provided with a hub 9 secured fast to the spindle 2 by suitable means such as a setscrew 10, and having an arm projecting at one side formed with the upright extension 11. Projecting from the opposite side of the hub 9 is an arm 12 carrying a weight 13 at its outer end which acts to counterbalance the arm 11 to provide for high speed rotation of the flier.

Rotatably mounted on the spindle 2 above the hub 9 of the flier 3 is a sleeve or carrier 15 for holding the cop or bobbin C of yarn or other strand-material. The cop C, as herein shown, consists of a cross-wound package wound in multiple with a plurality of strands laid in a flat tape or band. The cop or package C is usually wound on a paper tube 0 which fits over the sleeve 15 and seats at its lower end against an enlarged head or flange 16 thereon. Fiecured to the side of the upright arm 11 of the flier 3 is a. wire pigtail-giiide 17 held in place by a screw 18. At the top of the arm 11 is a second pigtail-guide 20, the tape of strands y being adapted to draw oft from the package G through the guide 17 and thence up through the pigtail 20.

The upper end of the spindle 2 is formed. with a relatively large axial counterbore 22 adapted to serve as a socket, for the nosepiece or extension 25 through which the wire or other core to draws during the operation of wrapping the strand-material therearound. The nose-piece 25 is held in its socket 22 by suitable means such as a setscrew 26. The set-screw 26 extends through the side of a collar 27 which surrounds the upper end oi the spindle 2 and holds the sleeve 15 in place with its lower end bearing against the hub 9 of the flier 3, the collar being oi slightly less diameter than that of the barrel of the sleeve 15 in order that the cop-tube 0 may be slipped over it in placing it on or removing it from the spindle. The set-screw 26 is preferably of the headless type so as not to extend beyond the periphery of the collar, and projects through a hole in the: spindle 2 with its end binding against the nose-piece 25. its inner end is tapered and formed with a concavity providing asharpened edge which bites into the surface of the nose-piece 25 to securely hold the several parts rotatively in connection, see l. The screw 26 is provided with a hexagonal socket at its outer end into which a suitable wrench may be inserted for turning the screw- The nose-piece 25 is formed with a tapered concavity 29 at its lower end to facilitate the insertion of the wire therein, and continuing upwardly therefrom is an axial bore 30 through which the wire to draws. Midway of its extremities the nosepiece or spindle-extension 25 is milled oil on its side to provide a substantially halfround section 31 as shown most clearly in Figs. 1 and 5. The nose-piece 25 is cut back from its forward side nearly to its vertical axis, but sufiicient metal is left to provide a shallow groove 33, see Figs. 2 and d, which forms an extension 01"? the axial bore 30. Where the rose-piece 25 is cut away at 31 the shouldered end of its lower or butt portion is beveled oil on its opposite sides to form guiding-faces 32 -for the strands of wrapping-material to prevent them from sliding down on the section 31. Above the collar 2'? the forward side of the nose-piece 25 is milled through with a slot 34*. opening into the axial bore 30. A slight distance above the point where the nosepiece is cut away to form the half-round section 31 suiiicient metal is left to extend outwardly in a flange 35 which is milled with a slot 36 opening into the axial groove 33. The flange 35 serves as a guide for preventing the wire from becoming laterally displaced from the groove 33. Above the flange 35 the nose-piece '25 is flatted or beveled oil on the sides as indicated at 37, this portion of the nose-piece cooperating with the polisher which irons the insulation into place and smooths it out on the wire in the manner and for the purpose as later more fully explained. It will be under- SJOOCl that the nose-piece or spindle-extension 25 is made detachable in order that it may be removed and replaced by a similar element having a wire-receiving bore and channel of different size to accommodate wire or other cores of smaller or larger diameter.

My improved strand-guide and polisher, which form component parts of the nosepiece attachment. are preferably moan-ted on a collar 40 which surrounds the nosepiece 25 above the collar 27 on the end of the spindle 2. The collar 40 may be held in pcsition on the nose-piece 25 by means of one or more set-screws l1 shown in detail in .4 l. The collar 40 is provided with a vertical threaded hole 42 adapted to receive the threaded end of a guide 4% formed with a hook at its upper end through which the strands of yarn g or other material lead as they draw from the pigtailnuide 20 on the flier 3. The guide 44 is locked in place by a check-nut l5 and is adapted for adjustment in position in accordance with whether the nose-piece and strand-guide are being used for a right or left-hand wrap. At the opposite side of the nose-piece 25 the collar 4G is provided with a larger tapped holelS for receiving the threaded end postor standard 47 which serves as the support tor the polisher-arm 50 to be later des .r'ibec The post d? is formed with a he portion L8 for receiving a wrench by cans of which it is screwed into the cellar 4i and adjusted in position, and a cheernut 49 at its lower end serves to lock in place. The upper end of the post l? is reduced in diameter at 51 and screw-thread ed at its end. Mounted to turn on the reduced portion 51 of the post 47 is the polisher-arm 50 which is provided with a lateral hole 53 at its end. The polisher-arm 50 is held in place on the post 4:? by means of a thumb-nut'5 l screwed onto the threaded end of the post, and the hub 55 of the arm is extended rearwardly to form a centrifugal compensating weight 56, see Figs. 2 and 5. The weight 56 has a fiat surface on its inner side extending perpendicularly to the back of the arm 50, but on its outer side it is rounded substantially in conformity with the cylindrical periphery of the collar 40, the object of this construction being to adapt the polisher-arm and its weight to fall within the circumferential confines of both the collars 27 and 10 so that the cop-.

tube 0 can he slipped on and oli over the polisher without removing any of the parts of the device.

The polisher proper consists in a flat rectangular presser-plate 60 carried on the swinging polisher-arm 50. Projecting from the back of the presser-plate 60 is a. pin or stud 61 which fits loosely within the hole 53 in the arm. 50, see Figs. 1 and 2. A. pin 62 driven through a lateral hole in the stud 61 holds the presser-plate away from the arm 50 and permits a slight rocking movement thereof whereby the polisher may accommodate itself to the surface of the wrap ping on the wire to, see Fig. 2. A second pin 64 driven through the outer end of the stud 61 holds the Presser-plate in assembled relation on the arm 50 to prevent its disconnection therefrom when the arm is swung back from the nose-piece 25. One of the lateral edges of the plate 60 lies alongside the flat inner side of the centrifugal weight 56 whereby to prevent the polislrer from turning on the axis of its stud 61 which projects through the arm 50.

Coiled around the lower portion of the vertical post 17 is a helical wire spring 65 having its lower end anchored in a hole 66 in the enlargedhexagonal portion 48 of the post 47. The upper end of the spring 65 is inserted in a vertical hole 67 in the centrifugal weight 56 on the polisher-arm 50. The hole 67 extends clear through the weight 56 so that when the polisher is reversed in position on the post 47, to adapt the machine to wind with a left-hand wrap as shown in Fig. 3, the spring can be connected with the polisher-arm in the manner as hereinafter more fully explained. It will be understood that the spring 65 is held under tension to cause it to act on the polisher-arm.

50 to urge the polisher 60 toward the axis of the nosepiece 25 whereby'the poli'sher bears against the wrapping being applied to the wire drawing through the nose-piece, see

Fig. 2. The tension of the spring 65 may be adjusted to vary the amount of pressure applied to the polisher by turning the post 47 in its hole in the collar l0. For this adjustment the check-nut 49 is first released and then the post is turned one way or the other to either wind up the spring to increase its tension or to unwind it to lessen its tension.

Having now described a preferred form of construction of the invention its method of operation will next be explained; In preparing the machine for operation a cop, bobbin or package G or yarn, silk or other strandmaterial is placed on its holder or sleeve 15 by slipping its cop-tube 0 over the nose-piece and its attached parts from the top. It will be understood that the cop-holder or sleeve 15 is rotatable with respect to the spindle 2 so that the material may be unwound from the cop C as it draws to the wrapping-device, and usually a braking-means is provided to check the rotation of the cop with respect to the spindle whereby to apply the proper tension to the strands drawing of? from the cop. Any suitable friction braking-means may be used for this purpose, but as such devices are well known in the art they are not herein shown or described. The tape 3 composed of multiple strands or filaments l of textile or other material is led off from the cop C through the guide 17 on the flier 3, and thence up'through the pigtail-guide 20 to the hook-guide 44 carried by the collar 40. The wire to or other core to be covered is inserted in the bore of the hollow spindle 2 and carried up through the axial bore 30 of thenose-piece 25, thence passing through the slot 36 in the guide-flange 35 and drawing through the channel or groove 33 with the polisher 5O pressing against its side, see Figs. 1 and 2. From the nose-piece 25 the wire leads to a suitable take-up or windingon reel, not herein shown, which is operated from the machine to draw the wire through the covering device at the prescribed rate of speed.

The end of the tape of strands y is twisted around the wire to to secure it thereto so that as the flier 3 is revolved with the spindle 2 the strands will be wrapped around the wire in the manner as well known. to those versed in the art. As the tape of strands 1 draws from the pigtail-guide 20 through the hookguide A l the latter acts to flatten the tape and spread the strands before they lead to the wire ea. As shown in Figs. 1 and 2, the tape of strands g draws across the rounded section 31 of the nose-piece 25 to spread the tape to greater width whereby it will be smoothly applied to the surface of the wire with the individual strands in parallel contiguous relation illustrated in Fig. l. The beveled shoulder 32 at the upper end of the butt-portion of the nose-piece 25 serves as a guide orabutmentto prevent the strands from winding down on. the. wire should such a tendency be present and the relation between the hook-guide 4A1 and the guiding face 32 may be adjusted to provide for the proper cooperation between the parts. As the strands y are twisted; or wrapped around the wire to the latter draws up through the slotted guide-flange 35 and is restrained thereby from vibrating or: chattering in the nose-piece so that. the wire will not become c stallized or made brittle as is sometimes the case in dvices where no: means are provided for preventing the latcral vibration of the wire under high speed operation. The strands of covering-material are wrapped smoothly and uniformly around the wire at the proper pitch or lead inaccordance with the number of strands being used and the size of the yarn or other material, the deviceb'eing adjustable to regulate the lead of the wrap by raising or lowering the nose-piece, or by r-tdjus-ting'the height or the guide As the wrapped wire passes under the polisher 60 the pressure. of the latter on the covering acts to straighten the strands and to iron them into place so that any kinks bunches or other irregularities occurring will be eliminated and the covering. smoothed and polished to insure a proper finish on its surface. The pressure of the polisher. against the covering on the wire is reg.ulated by varying the tension of its spring 65 which is adjusted by rotating the post 47 in one direction or the other in accordance with the requirements.

The polisher is maintained bearing against the yarn with a constant pressure at the. maximum speed of rotation of'the. device dueto the peculiar action of the centrifugal weir i 5-6 which counterbalances the effect of centrifugal force. The centrifugal weight on the polisher-arm forms a most essential and important feature of the improvement and is believed to be entirely novel as ap plied to the present use. The weight is designed to prevent the Polisher-arm from swinging outwardly away from. the. wire under'the influence of centrifugal force during high speed operation. In other words, theweight acts as an efficient counterp'oise' to maintain the spring 65 active with a. constant tension. so that the pressure brought to bear on the wrapped wire or other material is at all times uniform and suliicent for the purpose intended. Tt has been demonstrated that where heretofore in the art the speed of the wrapping head with its revolving flier has been limited. to considerable extent by the capacity of the polisher under the effect of centrifugal force, in the present improvement a much increased speed is possible due to the counterbalancing of the polisher whereby its pressure is maintained constant and uniform at all times; facht'he pres-- sure of the polisher may be controlled to; get the maximum. effect: at. a speed far in excessof that of any type of similar device. heretofore used in the art;

The peculiar form. of nose-piece as; above described also-constitutes an important improvement in the art. First it holdsthe wire from vibrating or. chattering as it. passes through the covering-device and, furthe r it acts to distribute the covering-strands on the wire with a maximum width of tape without separating the Stl'lIIClSy while pres venting them. from crowding, bunching: or kinking.v The curved? guide 4% acts as the;- initial' spreader for the strands of' the tape, and the. convex section 31 of thenose-p1iece serves as the final flattening or' spreading, guide as the strands draw thereacross with an extended contact thereon. It is also; to

be noted. that the guide;- 443 is placed close" to the nose-piece 25 in orderto prevent. the tape of insulatingor covering materia-l from whipping or vibrating, so that the strands cannot become alternately slack and tight,. but are applied to. the wire with a uniform tension to obtain. a: maximum. cover ing capacity for a given amount of'material- The abutment or shoulder 82' on the noses piece 25 prevents the strands from separating and running down on the wire-,. liable. to cause open places and faults in: the insulation, the tape being maintained. with the strands always. laid: in contact to completely cover. the wire. The polisher 60 being'rocke ably mounted on its. arm 50is. rendered. selfalining so that it always. contacts properly with the covering. on the wire with a manhmum of smoothing effect- As a further feature of improvement the device is adjustable for rightor left-hand. wrapping and practically no alteration in or substitution of new parts is required for this. purpose. Fig; 1 shows the device adjusted: for covering thev wire with a right-hand wrap. and when it is desired to put the coveringmaterial on with a left-hand wrap the parts are set as shown in Fig. 3. that is necessary is. to reverse the position of the parts as. follows: The collar 40 is removed from the nose-piece 25 and turned the other side up so that the holes for the post Q7 and heelguid-e 4A willbe in reverse position on opposite sides of the nose-piece. The guide li isthen applied: to place. with itshook extend-- ing rearwardly with respect to the front of. the nose-piece 25. The polish-er-arm is reversed in position on the post 47,. and the post is then screwed into the collar and locked in place by means of its check-nut 49. In. reversing the position. of the arm 50/ this part is simply turned bottom side up and, preferably, a spring of opposite wind issub stituted for the spring so that when the. polisher is forced away from the nose-piece.

525 the tendency will be for it to wind up the spring.

It will be observed by reference to Fig. 2 that by adjusting the collar 47 about the axis of the nose-piece 25 the post 47 will be brought intosuch position that the polisherarm 50 will assume the proper relation to the upper end of the nosepiece. That is to say, it is essential that the arm shall extend substantially at right-angles to a medial plane bisecting the reduced portion of the nose-piece. When it is desired to cover wire of larger or smaller diameter a different nose-piece is substituted with the proper size bore 30 and guiding-groove or channel 33. lVhen a larger wire is being covered the collar 40 is rotated counter-clockwise, and vice Versa with a smaller wire, to bringthe post 47 into such position that the polisher 60 will be maintained tangent to the surface of the covered wire without danger of its contacting with the nosepiece itself. This feature is most important, that is, the adaptability of the polisher for adjustment in conformity with the size of the wire being covered so that it will always contact with the coveren surface of the wire away from the nose-piece withoutdanger of its bearing on the nose-piece itself which would be liable to cause its pressure to be diminished, or in some cases entirely removed. It will be observed from the above that the device is readily adjusted for either a rightor lefthand wrap of the material on the wire and no parts need to be added or substituted for those already applied to the mechanism.

The present improved device provides for high speed operation, while insuring a high quality of product, and also makes for greater economy in the insulating-material employed per foot or pound of wire being wrapped. The covering is applied more smoothly and with greater uniformity, there by enhancing the appearance of the finished product and also providing for a higher d1- electric strength in the insulation without any chance for the appearance of bare places or faults. Moreover, my improved device is adapted for using larger sizes of cotton strands than generally employed, the pressure of the polisher acting to flatten the individual strands to increase the width of the tape and thus making for further economy in the material employed for wrapping. The complete device is particularly eflicient in operation and proof against derangement or getting out of order, while being adapted for a wide range of operation in insulating wire or other conductors, for covering elastic cords and for polishing twisted paper or fiber twine.

lVhile I have herein described and illustrated a preferred form of the invention as applied to use on a wrapping-machine, it is to be understood that the improvement is also adapted for other purposes. For instance, as before'mentioned, it may be used to great advantage on twisting-machines for polishing cords or paper and fiber twine, and also for similar use in finishing materials of a like nature such as braided cords or coverings. It is also to be understood that various modifications may be made in the structure and arrangement of the parts of the device without departing from the spirit or scope of the invention.
